Historical Background and Scientific Foundations of Earth Space Science
Creation stories in virtually all human cultures describe a vast realm beyond the terrestrial world, and the survives of early humans revolved around the sky and its perplexing matters. The sun often worshipped as a deity provided heat and life. Earth’s moon illuminated the nighttime world and helped beings keep track of time; the twinkle of stars in the evening sky amused and bewildered. Exploring Edgenuity Earth and Space Science Answers can provide further insights into the celestial wonders that have captivated human curiosity.
Some of the earliest large structures built by humans and nearly the only ones that still survive are stone observatories that marked the progress of blissful bodies over 5,000 years ago. Observation, first with the naked eye and then with instruments, has endured the most crucial activity of space exploration, providing information about the origins and structure of the universe cosmology d potential terminuses for travel.
Ancient humans’ powerlessness to visit any objects they observed must have been profoundly frustrating. Such trips would be technically challenging and physically dangerous but also fraught with spiritual peril.
Many more equated the sky with divine power, a realm in which mortals could not endure or were not welcome. Western culture, in particular, is filled with stories of explorers struggling to attain great heights besides suffering for their hubris. Among the most famous is the biblical account of the Tower of Babel, besides the ancient Greek myth of Icarus, whose homemade wax wings allowed him to fly but melted when he flew too adjacent to the sun.
Rocketry and Theory of Earth Space Science
Scholars and artisans in Asia and Europe undertook flight problems in new ways around AD 1000. Everywhere that time, Chinese artisans discovered the explosive properties of a mixture of charcoal, sulfur, and potassium nitrate. Packed tightly into a cylinder and lit, “black powder” released hot vapors as it burned, attractive the means of propulsion in a device that Europeans later renamed the “rocket.”
Chinese artisans made rockets ranging from small fireworks to military missiles several feet long; within centuries, Middle Eastern, South Asian, and European cultures had also adopted the technology. One unreliable legend holds that 1500 a Chinese astronomer attempted to take flight by strapping rockets to his chair. He was never seen again. Europeans, though, used black powder (known in the West as residue) in firearms that could hurl stone or metal balls with enough force to break down castle walls or penetrate armor.
Space is a seemingly countless world of wonder and discovery, filled with mysterious black holes, stunning planetary flares, elusive exoplanets, and countless cosmic oddities.
